HEADLIGHT.

Application filed April 11, 1921. Serial No. 460,206.

T 0 all whom it'may concern: I,

Be it known that 1, JOHN BRUEGKER, a citizen of the United States residing at Fort \Vayne, in the county of A len and State of Indiana, have invented new and useful 11nprovements in Headlights, lowing is a specification.

The invention relates to headlights and particularly to means for eliminating glare from motor vehicle headlights.

The object of the inven ion is to provide a simple and inexpensive of which the foldevice readily attachable to a headlight by which all glare from the headlight is eliminated without diminishing the intensity of the beam of light delivered by the same, the device also causin the roadway immediately in front of the ve icle to be indirectly illuminated.

The invention consists in an apertured frame supporting a plurality of bands of ribbon or tape extended across the entire aperture in spaced parallel and horizontal relation, the frame posed within the headlight adjacent the rear side of the lens, so that the bands transversely are parallel to the longitudinal axis ofpthe headlight and to all rays of light .delivered by the headlight which are parallel to said axis.

In the accompanying drawings I have illustrated an embodiment of the invention, in which- Figure 1 is an vice; Fig. 2 a central cross-sectional view 0 the same, and Fig. 3 aview of a headlight partly broken away and having the invention applied thereto.

Referring to the drawings, 10 indicates a headlight of usual form, 11 the parabolic reflector, 12 an electric lamp, 13 the seat for the lens, 14 the lens and 15 the rim attached to the body of the headlight and securing the lens in position.

The invention comprises a support or frame 16 formed preferably of sheet metal of suitable gauge. the central portion of which is apertured to correspond to the contour of the inner edge of the rim 15. The majority of headlights are circular at their front end, hence the frame for such headlights will be in the form of a ring as shown in Figs. 1 and 2. the central opening 17 of which is also circular. The outer portion of the ring is flat so that it may contact with the lens and be engaged between the lens and scat l3. .\djacent the central opening elevational view of the debeing adapted to be dis- 17 the ring is bowed inwardly to provide space between the ring andthe lens for the heads 18 of pins 19 extending through apertures formed in the ring. The pins, however, could be secured to the ring without heads and thereby obviate bowing of the ring; The manner of securing the pins to the ring is a matter of choice.

Pins 19 project at right angles to thering and they are arranged adjacent the inner .edge of thering, those pins on one side of thevertica-l axis of the ring being staggered with respect to the pins on the opposite side of said axis. The pins are substantially of uniform diameter and are so spaced apart on each side of the vertical axis of the ring I prefer to use a linen or cotton ribbon or tape of suitable width.

Since the bands of the ribbon or tape are parallel to the longitudinal axis of the headlight, all rays of light projected straight f forwardly by the headlight pass through the spaces between the bands. All oblique rays except those which pass through the several spaces are cut. off by the bands. The broken lines a and Z) in Fig. 3 indi cate the maximum range of oblique rays that pass through the space between any two bands. Hence a person'in front of the headlight will see the rays projected through the several spaces and between lines a and b of each space. None of these rays produce any glare whatsoever, since the headlight is adjusted so that line a is horizontal. It is evident that the greater the width of the bands the less will be the inclination of the headlight, and also that the greater the distance between the bands the greater will be the inclination of the headlights.

The bands, however, cause an indirect light to be shed on the ground in front of the vehicle and extending laterally for some distance thcrci'rom which appear as horizontal bands on the ground and seemingly llO , of the vehicle and give a view of the same 5f to the driver.

The intensity of the beam of light projected forwardly bythe headlight is not diminished by the bands of ribbon but it is concentrated on the road at the usual distance in front of the vehicle Without any blinding effect upon the eyes of the driver of an approaching vehicle.

The ribbon bands are preferably in one piece of material, but they may be formed of separate pieces of the material cut in proper lengths and secured to the pins.

The headlight is mounted to tilt in a vertical plane and the bands are fixed in their parallel relation to the longitudinal axis of the headlight. Hence after the bands are installed the headlight is adjusted until all oblique rays above the selected lineare cut off by the bands, the selected line being first determined by the Width and spacing of the bands, and then by adjusting the headlight the said line is established permanent'y in. a horizontal direction. At the same time the bands, being non-lustrous, produce no glare-but cast an indirect light upon the ground in front of the headlight.

What I claim is:

1. In a headlight, a fiat ring abutting the ly, said bands being parallel to the longitudina] axis of the headlight.

3. In a headlight, a frame supported Within the headlight having a central aperture conforming to the contour of the exposedportions of the outer face of the lens of the headlight, a series of pins secured to the frame about said aperture and extending rearwardly from the frame, and a fabric ribbon laced on the pins and\ extending across said aperture in horizontal bands,

the pins being so arranged that the} said-- bands are uniformly spaced apart and} parallel to each other and to the longitudinal axis of the headlight. p i

In Witness whereof, I have hereuntd subscribed my name this 9th day of April, 1921.
